The Grumman F9F/F-9 Cougar was a carrier-based fighter aircraft for the United States Navy and United States Marine Corps. Based on Grumman's earlier F9F Panther, the Cougar replaced the Panther's straight wing with a more modern swept wing. Thrust was also increased. The Navy considered the Cougar an updated version of the Panther, despite having a different official name, and thus Cougars started off from F9F-6.

Prototypes were quickly produced by modifying Panthers, and the first (XF9F-6) flew on 20 September 1951. The aircraft was still subsonic, but the critical Mach number was increased from 0.79 to 0.86 at sea level and to 0.895 at 35,000 ft (10,000 m), improving performance markedly over the Panther. Instead of using conventional ailerons for roll control, the F9F-6 uses spoilers on the upper surfaces of the wing.
Wing fences were soon added and the spoilers extended from the fences to the tips of the wing. The rudder pedals controlled the part of the rudder below the horizontal tail surface, while the upper portion of the rudder was controlled by a yaw damper. This allowed the Cougar to fly safely and easily without the upper portion of the tail.

The U.S. Navy's flight demonstration team, the Blue Angels flew four different variants of F9Fs from the F9F-2 Panther to the F9F-8. The Blue Angels replaced their six F9F-5 Panthers with six F9F-6s in 1953. This was short lived however and the Navy subsequently took them for fleet use without using the planes in an air show.
The F9F-6s were then replaced with overhauled F9F-5s until 1954 when the Blue Angels switched to the F9F-8. The Blue Angels used the F9F-8 until 1957 they were replaced by the Grumman F11F-1 Tiger, although one two-seat F9F-8T was retained for press and VIP flights.
